Last night I updated my regular 3ds to the latest firmware to play Mario 2 and I updated my flash card as well to 1.17. The dstwo worked fine on the 3ds after I updated. Today I traded the 3ds for the xl and now the dstwo is not working on the xl. I tried it on my ds lite and it works so it can't be broken. Any ideas of what could be wrong? I thought the dstwo works fine on the xl since its the same firmware.
